Y Lines Only – Forward and Reverse
Using the Forward and Reverse survey format, Y line data are collected in the pattern
shown in Figure 6-10.
When data are collected like this, it is important that lines start and end on established
baselines, otherwise, when lines are reversed to the correct orientation for the display,
they may be offset from one another.
Figure 6-10: For collecting GPR data consisting of
long data lines it makes more sense to follow a
forward and reverse surveying pattern. For the final
data to be spatially correct with a minimum of editing,
data collected in this pattern should be on lines that
extend completely from one baseline to the other.
